If the TL/SP level you are going to update is older(build/release date)
than the SP level which is currently installed.For instance: You are
currently at "AIX 5.3 TL6 SP8"(5300-06-08-0831) which was released in 31st
week of 2008, and you are trying upgrade to TL7 SP1 which was released in
November 2007(that means released earlier than TL6 SP8) , then you would
definitely encounter the build date issue.
So the solution is to verify build dates referring to the TL release chart
& then update to the latest level.In this above case, we have to upgrade it
to TL7 SP6/SP7.
